Description

For sample children under 18 years old who have an immunization record and who have at least three Hepatitis B vaccines on their record, IMRHEPBDA3 reports the day when the person received his or her third Hepatitis B vaccine.

Users should combine IMRHEPBDA3 with IMRHEPBMO3 and IMRHEPBY3, which reports the month and year of the person's third Hepatitis B vaccine, in order to get the complete date when the person received his or her third Hepatitis B vaccine.
